Semiconductor device, operating condition controlling method, and non-transitory computer readable medium

An operating condition controlling method comprising:

• referring to a performance table representing a relationship between an operating condition of a process execution unit configured such that the operating condition can be varied and a processing capacity of the process execution unit, and extracting one or more operating conditions associated with a processing capacity having a predetermined relationship with respect to a reference processing capacity;
• when one operating condition is extracted, changing the operating condition of the process execution unit to the operating condition extracted;
• and
• when a plurality of operating conditions are extracted, referring to a power consumption table representing a relationship between the operating condition and power consumption and identifying an operating condition with the lowest power consumption among the plurality of operating conditions, and changing the operating condition of the process execution unit to the operating condition identified,
• wherein the power consumption related to the operating condition in the power consumption table includes a leak power depending on a temperature,
• wherein the process execution unit comprises a plurality of processors configured such that an operating frequency can be varied,
• wherein the operating condition includes a combination of a number of processors to operate in the process execution unit and an operating frequency of the processors, and
• wherein a number of the processors to operate in the process execution unit and an operating frequency of each of the processors is determined based on referring to the performance table and the power consumption table.

A Non-transitory Computer Readable medium storing a program causing a computer to execute operating condition controlling, wherein the operating condition controlling comprises:

• referring to a performance table representing a relationship between an operating condition of a process execution unit configured such that the operating condition can be varied and processing capacity of the process execution unit, and extracting one or more operating conditions associated with a processing capacity having a predetermined relationship with respect to a reference processing capacity;
• when one operating condition is extracted, changing the operating condition of the process execution unit-to the operating condition extracted;
• and
• when a plurality of operating conditions are extracted, referring to a power consumption table representing a relationship between the operating condition and power consumption and identifying an operating condition with the lowest power consumption among the plurality of operating conditions, and changing the operating condition of the process execution unit to the operating condition identified,
• wherein the power consumption related to the operating condition in the power consumption table includes a leak power depending on a temperature,
• wherein the process execution unit comprises a plurality of processors configured such that an operating frequency can be varied,
• wherein the operating condition includes a combination of a number of processors to operate in the process execution unit and an operating frequency of the processors, and
• wherein a number of the processors to operate in the process execution unit and an operating frequency of each of the processors is determined based on referring to the performance table and the power consumption table.
